module_enable_x() has nothing to do with CONFIG_ARCH_HAS_STRICT_MODULE_RWX allthough by coincidence architectures who need module_enable_x() are selection CONFIG_ARCH_HAS_STRICT_MODULE_RWX. Enable module_enable_x() for everyone everytime. If an architecture already has module text set executable, it's a no-op. Don't check text_size alignment. When CONFIG_STRICT_MODULE_RWX is set the verification is already done in frob_rodata(). When CONFIG_STRICT_MODULE_RWX is not set it is not a big deal to have the start of data as executable. Just make sure we entirely get the last page when the boundary is not aligned. And don't BUG on misaligned base as some architectures like nios2 use kmalloc() for allocating modules. So just bail out in that case. If that's a problem, a page fault will occur later anyway.
